[0007] As a further solution of the present invention: an engagement groove is provided on the inner surface of the copper sleeve, and the driving gear is located in the engagement groove and engages with the engagement groove.

[0008] As a further solution of the present invention: a screw rod is fixedly connected to one side of the shaft sleeve, and the screw rod extends into the threaded sleeve and is threadedly connected to the threaded sleeve.

[0009] As a further solution of the present invention: one side of the sleeve is fixedly connected to a limit rod, the limit rod extends into the rotating ring block and is in sliding contact with the rotating ring block, the limit rod limits and supports the sleeve, and a plurality of slots are opened on the other side of the sleeve.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the device is sleeved on the cylindrical surface of the bearing, and according to the bearing, the push rod is pushed, and the push rod drives the rotating ring block to rotate. When the rotating ring block rotates, the rotating ring block drives the threaded sleeve and the driving gear to rotate. Since the driving gear is located in the meshing groove and meshes with the meshing groove, as the rotating ring block drives the driving gear to rotate, the driving gear rotates under the action of the meshing groove, and the driving gear drives the threaded sleeve to rotate. Since the threaded sleeve is threadedly connected to the screw rod, when the threaded sleeve rotates, the screw rod moves, and the screw rod drives the shaft sleeve to move so that the shaft sleeve and the bearing fit together, the shaft sleeve can be fixed to bearings of different diameters. The device can fix bearings of different diameters, which is convenient for bearing installation and disassembly. BRIEF DESCRIPTION OF THE DRAWINGS
